A Brief Introduction to Laboratory Management in Concrete Enterprises

The laboratory is not only the main department for controlling the quality of concrete, but also an important department for technological development and development.

It is also the window for the external image of the enterprise and the core department of the concrete enterprise.

Ferrule Loop Insert

The concrete enterprise laboratory not only needs to conduct re inspection of the materials used in concrete, but also supervises and controls the quality of concrete production, playing a key role in the development of new products and technologies, cost control, and technical services.

The quality of its personnel, testing equipment, and technical management level represent the level of quality management of ready mixed concrete.

Five misconceptions about watering and curing concrete

Watering and curing of concrete is a crucial step in the entire process of concrete construction, which directly affects the adequacy of cement hydration reaction, the normal development of concrete strength, and durability.

Steel Chamfer

The essence of cement hydration reaction is the complex chemical reaction between cement clinker minerals and water, which needs to be completed in a continuously moist and suitable temperature environment.

Watering and curing are the core means to create necessary conditions for this reaction.

However, in practical engineering practice, due to deviations in the understanding of concrete material characteristics, hydration mechanisms, and maintenance technical specifications by construction personnel, they often fall into various misconceptions about maintenance, resulting in quality hazards such as early cracking, insufficient strength, and decreased durability of concrete.

Literature Sharing 89: Design of Recycled Concrete Mix Proportion Based on Ensemble Algorithm and Multi Objective Optimization

Recycled concrete has become a research hotspot in the field of civil engineering due to its ability to achieve the resource utilization of construction waste and reduce carbon emissions.

However, its mix design is affected by multiple factors, and traditional testing methods have problems of high cost and low efficiency.

Today, I would like to share with you a latest study published in Construction and Building Materials.

Rebar Wheel Spacers

This study combines machine learning and genetic algorithms to construct a multi-objective optimization model for recycled concrete mix design, providing efficient and scientific design ideas for the engineering application of recycled concrete.

The secret that tunnels won’t collapse? Take you through a picture to understand the four martial arts skills of “shotcrete”.

Dear testers, take a few seconds to say something! Previously, I used multiple download methods to share PPT, but the results were not very satisfactory – especially the Baidu Cloud link, which not only frequently failed, but also had to be transmitted from both the website and cloud storage, adding a lot of extra workload.

The results showed that with the increase of steel fiber content, the 28 day flexural strength and compressive strength of the specimens increased; With the increase of basalt fiber content, the 28 day flexural strength of the specimen significantly improves, while the increase in 28 day compressive strength is relatively small; Under the same dosage, the improvement effect of steel fiber on the mechanical properties of UHPC is better than that of basalt fiber.
